Index in backup mode while event show the opposite?

Hi All,

I have an EV server installed, backed up by NBU with EV agent for NBU Backup.

All backup are successful, and events in EV server show:

Successfully cleared backup mode from the following index location.

Enabling additions, deletions, and updates because the index location is not in backup mode.

Index Location: E:\Index\index3

(8 repeating events for 8 index locations),

However – EV monitor states that index is in backup mode, and when checking in VAC the Indexing services – they are marked on backup mode.

So – I take them out of backup mode manually.

Anyone knows what can cause the events to say that backup mode cleared while actually still in backup mode?
